Explosion-Proof Multi-Turn Absolute Encoder A/80EXS

Manufacturer: ELCIS Encoder
Category: Encoder, Absolute Encoder, ATEX Absolute Encoder, SENSORS

24 or 25-bit absolute multi-turn encoder, explosion-proof Ex d II C T6, ISSeP approved according to CENELEC standards, with servo-type flange. Suitable for use in potentially explosive atmospheres (except firedamp), with markings II 2 G Ex d IIC T6 and D Ex tD A21 IP6X T85°C.

Resolution of 4096 steps per revolution (12-bit) in 4096 revolutions (12-bit) or 8192 revolutions (13-bit), in Gray code, with magnetic sensors. SSI serial interface with RS422 transmission and clock frequency of 100 kHz to 2 MHz. Ordering resolution: 12 (Gray 4096 × 4096) or 13 (Gray 4096 × 8192).

Aluminum base and anodized aluminum cover, stainless steel shaft Ø10 h7 and 1300 g weight. Connection via 1 m IP66 cable (CV3) or 26c IP65 cable end connector (VM5, TM5, only outside the explosion-risk area). Options: sealed bearings (Z), stainless steel housing (N), tropicalization (G), and variants according to specification (X). Special conditions for safe use (symbol X): cable suitable for a minimum temperature of 100 °C permanently connected to the encoder, with a suitable connection at its free end, and mounting screws of at least grade 8.8. Available in guemisa.es.

Technical Frequently Asked Questions

What electronic output and interface does the 80EXS multi-turn encoder have?

SSI serial interface (MS) in Gray code, with SSI serial electronics (5), RS422 transmission and supported clock frequency from 100 kHz to 2 MHz.

What resolution, axis, and power supplies does it support?

24 or 25 bit resolution: 4096 steps per revolution in 4096 revolutions (code 12) or 8192 revolutions (code 13). Stainless steel shaft Ø10 h7. Power supply 5 V ±10 % or 10÷30 V.

What connections and IP rating does it support?

1 m IP66 cable (CV3) or 26c IP65 cable end connector (VM5) and 26c sealed IP65 connector (TM5), these last two only for use outside of explosion-risk areas. Cable splicing must be done with an Ex junction box or outside of potentially explosive atmospheres. Shaft side: IP65 standard and IP66 with sealed bearings (Z). Ambient temperature T6: -20 … +40 °C; operating temperature: -20 … +70 °C.
